Course Overview

By the end of 2004, most corporate IT networks will incorporate wireless devices using IEEE 802.11 wireless LAN technologies (Wi-Fi). It is therefore now essential that data network consultants, planners, designers, and support staff to have in-depth skills and experience in 802.11 wireless networks.

This latest-edition Planet3-Certified course from this particular provider - the UKs leading company for training in wireless technologies - provides probably the most comprehensive hands-on practical coverage of IEEE 802.11 WLAN technologies available, in a 5-day fast-track format.

The course incorporates some 40 hours of training, comprising 30 lecture modules, and more than twelve hands-on practical labs, working with enterprise-grade equipment from a range of vendors.

The course provides expert guidance on Wireless LAN site survey, product selection, equipment installation, wireless network configuration, support, wireless LAN security and troubleshooting.

Audience

• IT professionals and network engineers responsible for installing or supporting 802.11 Wireless networks.
• IT professionals wanting to progress into the wireless network industry.
• Network planners, designers and support staff.
• IT Security staff, managers and auditors.
